On Mac:
* Open Finder
* Hold down COMMAND + SHIFT keys and press 'G'
* Enter "/private/etc/" in the field and press "Go"
* Find "hosts" file in the directory
* Drag the file to your desktop
* Open it in text editor
* Remove the line that has gs.apple.com entirely or put a # at the beginning of it to comment it out
* Save the file
* Drag it back to the /private/etc/ folder.
* You'd need to enter your username and password to authenticate the move

On Windows:

Locate the hosts file in one of the following directories:
Windows 95/98/Me c:\windows\hosts
Windows NT/2000/XP Pro c:\winnt\system32\drivers\etc\hosts
Windows XP, Vista, 7 c:\windows\system32\drivers\etc\hosts
Right click and click on "Open With..." and then click on "Notepad" on the list.
* Remove the line that has gs.apple.com completely and save the file.

This should work fine but you will lose all music, photos, videos and books :S

I thought I was doomed. I'd been messing around with this iPhone while trying to jailbreak an older phone a few weeks ago. I was convinced this had "goosed" this phone. Very simple instructions, I am so very grateful. Many thanks again.
